How many seeds per mu of alfalfa
It takes 8-12 jin of seeds to grow one mu of alfalfa. When planting, alfalfa seeds with high quality and full grains should be selected and the sowing depth should be kept at 1-2 cm.
The main points of alfalfa planting:
1. Selection of land and seed
Although alfalfa has wide adaptability, it can grow in all kinds of topography and soil. But the most suitable condition is sandy loam with soft soil and pH value of 6.5-7.5. In addition, when choosing seeds, you should buy full-grained and high-quality seeds from self-increasing merchants.
two。 Soil preparation and fertilization
The alfalfa must be carefully prepared before sowing. The best time for soil preparation is in summer, turn deeply, rake once, and turn the weeds into the deep. If there are many weeds before sowing in autumn, one more deep turning or rotary ploughing is necessary, and then rake flat to meet the sowing requirements. Before sowing, combined with soil preparation, organic fertilizer 2-3m2/ mu and pure phosphorus 8-16kg/ mu were applied once.
3. Sowing seeds
Autumn sowing is generally used in the areas where there are two crops a year in the north. Soil moisture is sufficient, temperature is suitable, and there are few weeds, diseases and insect pests. In Shaanxi, Hebei, Henan, Shanxi and Shandong, autumn sowing is the best, and the sowing time is from August 10 to September 10. Too late to affect the normal overwintering.
4. Field management
It should be watered before winter, after turning green and during drought. Coastal and low-injection land should pay attention to drainage in the rainy season. In addition, we should also do a good job in weeding and pest control.
Alfalfa can generally harvest 4 crops a year, and can benefit from sowing for 10 years. It is one of the widely used livestock feed, and the planting benefit is considerable.
